How many fans

Is it OK to run 3 fans off of the D9 port of the RAMPS board? I'm currently running 2, on opposite corners of the frame, and I occasionally have curling issues in the left rear - the farthest point from either fan.

The way I figure it, each fan draws about 0.25 amp, but the D9 circuit is intended to operate a hot end which can draw in excess of 2 amps. So it seems I ought to be safe to add a third, but I'm not an electrical engineer.
